The no-code WYSIWYG builder for next-gen interactive EPUBs. | Opkle(옵클)

Hi Product Hunt! 👋 I'm Chang-gyu, the founder of Opkle. I'm so thrilled to share Opkle Editor with you today! 🤔 Why I built this: As a creator and developer, I was frustrated by the limitations of traditional digital publishing. EPUBs are often just static text, and creating beautiful, interactive layouts required deep HTML/CSS knowledge. I wanted a tool that felt as intuitive as a graphic design app but outputted standard-compliant web and EPUB code. 🚀 What is Opkle Editor? It’s a no-code WYSIWYG builder that treats document creation like visual design. - 🎨 Photoshop-like Layers: Stack images and text freely to build complex layouts. - ✨ Instant Animations: Create and apply CSS animations directly in the editor. - ⚡️ Lightning Fast & Secure: Built purely with Vanilla TS and powered by IndexedDB. All your work stays local and private—no server lag. ✅ Built-in Validation: Automatic W3C error checking (epubcheck) and Ace by Daisy accessibility scans. 📦 Smart Optimization: Auto-compresses fonts and images to keep your files light. Whether you're creating a next-gen interactive EPUB3 or a responsive web page, Opkle Editor handles the heavy lifting so you can focus on creativity. I’d love to hear your feedback, feature requests, or answer any questions you might have. Let me know what you think in the comments! Thank you! 💙
